ABSTRACT

A vehicle cover assembly comprising; a flexible cover; one or more side rails; and a fastener assembly that is secured to a vehicle bed comprising; a cover fastener that is on one or more edge regions of the flexible cover; and a side rail fastener with one or more rows of fasteners comprising; a plurality of dual hooks on the base that releasably connect with the cover fastener of the flexible cover; and a plurality of spacers between the plurality of dual hooks.

FIELD

The present teachings relate to hook and loop fasteners, andspecifically, the hook and loop fasteners relate to a fastening meansfor vehicle bed covers.

BACKGROUND

Flexible vehicle bed covers generally are rolled across the vehicle bedand engaged by hoop and loop fasteners for quick and efficient coveringof the contents of the vehicle bed. Many flexible covers that use hookand loop fasteners tend to engage before the user has had a chance toevenly distribute the cover over the vehicle bed. When the flexiblecover is unevenly distributed on the vehicle bed, it is difficult toprotect the contents of the vehicle from inclement weather and theft,and untightened portions of the cover may collect fluid, which mayeventually ingress into the vehicle bed. Furthermore, every readjustmentof the flexible cover causes the hook and loop fasteners to degradefaster, which then requires replacement.

Examples of some hook and loop fasteners can be found in U.S. Pat. Nos.8,523,266; 8,167,353; 7,815,239; and 6,544,245 and YouTube videosTruXedo Titanium Hard Rolling Tonneau Features and Benefits, publishedon Jul. 17, 2015 and TruXedo TruXport Roll-Up Truck Bed Cover Featuresand Benefits, published on Jun. 6, 2017 all of which are incorporated byreference herein for all purposes. What is needed is a flexible coverthat will not pre-engage when the user rolls the flexible cover over thevehicle bed. What is needed is a flexible cover that will rest on sidesof the vehicle bed before the user is ready to engage the flexiblecover. What is needed is a flexible cover that requires an extra step oruser engagement to engage the flexible cover.

The row of fasteners may include a pluralityof spacers that may be elevated above the plurality of dual hooks, theplurality of opposing dual hooks or both such that the spacers preventpre-engagement of the strip of loop fasteners. The spacers maysubstantially prevent pre-engagement by elevating the cover fastenersabove the end fasteners (e.g., one or more ends of a hook may contactone or more loops but 10 percent or less or preferably 5 percent or lessof the hooks (e.g., front hook, rear hook, or both) may be in contactwith a loop). The row of fasteners may have a ratio of spacers to dualhooks of 1:1 or more, 1:2 or more, 1:3 or more, 1:4 or more, 1:5 ormore, 1:6 or more, or 1:7 or more.

The front hook of the dual hooks andthe front hook of the opposing dual hooks may face opposite directions.The dual hooks may alternate with the opposing dual hooks in the row ofthe fasteners. For example, a dual hook may precede an opposing dualhook, another hook may follow the opposing dual hook, and anotheropposing dual hook may follow the another dual hook so that the dualhooks and the opposing dual hooks form a pattern in the row offasteners. The dual hooks may alternate with the spacers in the row offasteners. The front hook, the rear hook, or both of the dual hooks mayengage with the strip of loop fasteners.

The connection lip may slope down intothe connection edge of the dual hook, opposing dual hook, or both. Theconnection lip and the strip of loop fasteners may connect such that theflexible cover is secure and engaged on the side rails and encased overthe vehicle bed. The connection lip may be sufficiently below the uppersurface of the spacer such that a force is needed to engage theconnection lip and the loop fastener. The connection lip and loopfastener may engage when a force is applied to the flexible cover suchthat the loop fasteners are pushed down past the elevated upper surfaceof the plurality of spacers and the top edge of the dual hooks. Theconnection lip may curve into a point, a rounded edge, a hooked edge, acrescent edge, or a combination thereof.

For the dual hooks, opposing dualhooks, or both, the distance from the connection lip of the front hookto the angled wall of the rear hook may define a total width of the dualhooks. The total width of the spacers and the total width of the dualhooks may be substantially the same. The total width of the spacer maybe less than the total width of the dual hooks such that the front hookof the dual hook protrudes past the side edge of the spacers.
